PdfGraphics.MeasureString(String, DXFont) Method
Measures the specified string when drawn with specified font parameters.
Namespace: DevExpress.Pdf
Assembly: DevExpress.Pdf.v24.2.Drawing.dll
NuGet Package: DevExpress.Pdf.Drawing
#Declaration
#Parameters
Name | Type | Description |
---|---|---|
text | String | A text to measure. |
font | DXFont | An object that defines font parameters. |
#Returns
Type | Description |
---|---|
Size |
The string’s measured size. |
#Remarks
Use this method to calculate a size of the drawn text. Use the returned SizeF object to calculate a page area or a point where you can draw text.
The MeasureString
method overload measures a string with 96 DPI. Use the PdfGraphics.MeasureString(String, DXFont, PdfStringFormat, Single, Single) method overload to obtain text size with 72 DPI to calculate its size on a PDF page.
#Example
using DevExpress.Pdf;
using System.Drawing;
using DevExpress.Drawing;
//...
using (var processor = new PdfDocumentProcessor())
{
processor.CreateEmptyDocument();
using (PdfGraphics graphics = processor.CreateGraphics())
{
// Obtain the first document page
PdfPage page = processor.AddNewPage(PdfPaperSize.A4);
PdfRectangle pageSize = page.CropBox;
// Specify text to draw
string text = "PDF Document API";
using (SolidBrush textBrush = new SolidBrush(Color.FromArgb(255, Color.DarkOrange)))
{
DXFont font = new DXFont("Segoe UI", 20, DXFontStyle.Regular))
// Calculate text size
SizeF textSize = graphics.MeasureString(text, font);
// Calculate a point where to draw text
PointF textPoint =
new PointF((float)((pageSize.Width - textSize.Width) / 2), (float)((pageSize.Height - textSize.Height) / 2));
// Draw text at the calculated point
graphics.DrawString(text, font, textBrush, textPoint);
// Add graphics content to the page foreground
graphics.AddToPageForeground(page, 72, 72);
}
}
processor.SaveDocument("result.pdf");
}
